Patent

CA 2022710

An improved die member and method of attaching a self-piercing and riveting fastener to a panel wherein a slug pierced from the panel by the riveting fastener is securely staked in the tubular riveting portion of the fastener during the installation of the fastener. The staking method includes shearing integral ribbons from the inside surface of the tubular barrel portion as the barrel portion is deformed radially outwardly in an annular die cavity of the die member. The integral ribbons are then preferably deformed radially inwardly in semicircular staking cavities defined through the free end of the central die poet. In the moat preferred method, radial tabs are simultaneously formed in the panel slug, which are deformed against an inside surface of the barrel portion, securely staking the slug in the tubular barrel portion and preventing inadvertent removal of the slug.
